Khakaure Senusret III (also written as Senwosret III or the hellenized form, Sesostris III) was a pharaoh of Egypt. He ruled from 1878 BC to 1839 BC during a time of great power and prosperity, and was the fifth king of the Twelfth Dynasty of the Middle Kingdom. He was a great pharaoh of the Twelfth Dynasty and is considered to be, perhaps, the most powerful Egyptian ruler of the dynasty. Consequently, he is regarded as one of the sources for the legend about Sesostris. His military campaigns gave rise to an era of peace and economic prosperity that reduced the power of regional rulers and led to a revival in craftwork, trade, and urban development. Senusret III was among the few Egyptian kings who were deified and honored with a cult during their own lifetime.

Senusret III was the son of Senusret II and Khenemetneferhedjet I, also called Khenemetneferhedjet I Weret (the elder). Three wives of Senusret III are known for certain. These are Itakayt, Khenemetneferhedjet II and Neferthenut, all three mainly known from their burials next to the pyramid of the king at Dahshur. Several daughters are known, although they also are attested only by the burials around the king's pyramid and their exact relation to the king is disputable. These include Sithathor, Menet, Senetsenebtysy, and Meret. Amenemhat III was most likely a son of the king. Other sons are not known.

The Pyramid of Senusret III (Lepsius XLVII) is an ancient Egyptian pyramid located at Dahshur and built for pharaoh Senusret III of the 12th Dynasty (19th century BCE).

The pyramid is the northernmost among those of Dahshur, and stands around 1.5 km northeast of Sneferu's Red Pyramid. It was erected on leveled ground and composed of a mudbricks core covered with a casing of white Tura limestone blocks resting on foundations. It was first excavated in 1894 by the French Egyptologist Jacques de Morgan, who managed to reach the burial chamber after discovering a tunnel dug by ancient tomb robbers. A more recent campaign was led by Dieter Arnold during the 1990s.

The original project included the main pyramid along with a northern chapel and a small eastern mortuary temple, all surrounded by an enclosure wall. Outside this enclosure were seven tombs belonging to Senusret's queens and princesses, and the whole complex was again surrounded by an outer wall; this wall was enlarged during the works in order to accommodate a large temple on the southern side and a causeway.

The remains of six sacred barques were excavated outside the outer enclosure on the southern side. The now-demolished eastern temple was very small in size, perhaps a sign of the decline of the traditional funerary cult, as Arnold suggested. On the remaining reliefs were depicted conventional scenes of offerings to the enthroned Senusret III. The southern temple was likely demolished during the New Kingdom and according to its foundations it consisted in a colonnaded courtyard and an inner shrine. The valley temple has not been discovered.

Many shaft tombs belonged to the royal women were discovered on the northern and southern sides of the main pyramid; it was believed that these shafts were topped by mastabas until Arnold in 1997 demonstrated that these consisted in the intricately rock-cut hypogea of seven small pyramids. Explorations of the northern tombs led to the discovery of the treasures of princesses Sithathor and Mereret (among these objects, the famous pectorals with the names of Senusret II, Senusret III and Amenemhat III now exhibited at the Cairo Museum), as well as the sarcophagi of princesses Menet and Senetsenebtysy and of queen Neferthenut.

Among the southern tombs, the easternmost was discovered in 1994 and its hypogeum led to a burial chamber located under the main pyramid. Here, a granite sarcophagus was found, along with some objects bearing the name of Khenemetneferhedjet I Weret, Senusret III's royal mother.

De Morgan struggled for months to find the original entrance; after digging several tunnels directed towards the center of the monument, he finally found the thieves' tunnel. One of the passages was covered by graffiti which were rather alien to the Egyptian canons, the most famous among these represents a human head with a striking hairstyle. De Morgan argued that the tunnels and the graffiti were made by Semitic grave robbers during the Hyksos occupation. From the thieves' tunnels, de Morgan was able to trace the original entrance.

From the entrance, located on the western side of the pyramid, a long descending hallway led to an antechamber which connects a storeroom on the west wall to the king's chamber on the east wall, the latter made from granite and provided with a granite sarcophagus on the western side, and a niche for the canopic chest on the southern one.

The granite walls of the burial chamber were whiten with gypsum. Above the chamber Arnold found three relieving vaults made from granite (the bottom one), limestone (the middle one) and mudbricks (the top one) which were meant to discharge the weight on the underlying chamber's walls in order to prevent a roof collapse.

The king's chamber contained pottery and a dagger, while the granite sarcophagus was empty. It is possible that Senusret III was never buried there and that he might have preferred his Abydene tomb as his final resting place, as suggested by the lack of a blocking system within this hypogeum.
